Intro
My right eye still can't see well. A high-pitched ringing remains in my left ear, and my fingertips occasionally tremble as if they aren't my own.
New surgical scars had increased on my body.
Cheers can be heard from the television by the bed.
"The long-standing Erosion Disaster has finally come to an end."
Guest gave a small laugh.
The world was saved.
People can go to school. People can work. People can fall in love and grow old with their families.
It was all what I had protected.
And then, I finally realized.
In that future, I am the only one missing.
—And now, Guest is running from the world they once saved.
